Using machine learning algorithm to predict the risk of post-traumatic stress disorder among firefighters in Changsha / 中南大学学报(医学版)

OBJECTIVES@#Firefighters are prone to suffer from psychological trauma and post-traumatic stress disorder (PTSD) in the workplace, and have a poor prognosis after PTSD. Reliable models for predicting PTSD allow for effective identification and intervention for patients with early PTSD. By collecting the psychological traits, psychological states and work situations of firefighters, this study aims to develop a machine learning algorithm with the aim of effectively and accurately identifying the onset of PTSD in firefighters, as well as detecting some important predictors of PTSD onset.@*METHODS@#This study conducted a cross-sectional survey through convenient sampling of firefighters from 20 fire brigades in Changsha, which were evenly distributed across 6 districts and Changsha County, with a total of 628 firefighters. We used the synthetic minority oversampling technique (SMOTE) to process data sets and used grid search to finish the parameter tuning. The predictive capability of several commonly used machine learning models was compared by 5-fold cross-validation and using the area under the receiver operating characteristic curve (ROC-AUC), accuracy, precision, recall, and F1 score.@*RESULTS@#The random forest model achieved good performance in predicting PTSD with an average AUC score at 0.790. The mean accuracy of the model was 90.1%, with an F1 score of 0.945. The three most important predictors were perseverance, forced thinking, and reflective deep thinking, with weights of 0.165, 0.158, and 0.152, respectively. The next most important predictors were employment time, psychological power, and optimism.@*CONCLUSIONS@#PTSD onset prediction model for Changsha firefighters constructed by random forest has strong predictive ability, and both psychological characteristics and work situation can be used as predictors of PTSD onset risk for firefighters. In the next step of the study, validation using other large datasets is needed to ensure that the predictive models can be used in clinical setting.

Objective:To investigate the risk factors for posthepatectomy liver failure (PHLF) in patients with hepatocellular carcinoma and construction of prediction model.Methods:The retrospective case-control study was conducted. The clinicopathological data of 116 patients with hepatocellular carcinoma who underwent hepatectomy in the First Affiliated Hospital of University of Science and Technology of China from January 2019 to January 2022 were collected. There were 99 males and 17 females, aged (59±10)years. Observation indicators: (1) occurrence of PHLF; (2) analysis of factors influencing the occurrence of PHLF; (3) construction and evaluation of prediction model for PHLF. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distri-bution were represented as M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. The univariate analysis was conducted using the corresponding statistical methods based on data type. Multivariate analysis was conducted using the Logistic regression model with forward method. The regression coefficient was used to construct the prediction model. The receiver operating characteristic curve was drawn, and the area under curve (AUC) was used to evaluate the predictive ability of prediction model. Results:(1) Occurrence of PHLF. Of the 116 patients, there were 27 cases with PHLF and 89 cases without PHLF, respectively. Of the 27 patients with PHLF, 13 cases underwent laparoscopic hepatectomy and 14 cases underwent open hepatectomy. (2) Analysis of factors influencing the occurrence of PHLF. Results of multivariate analysis showed preoperative portal vein tumor thrombus and preoperative indocyanine green retention at 15 minutes (ICG R15) ≥10% were independent risk factors influencing the occurrence of PHLF ( odds ratio=13.463, 4.702, 95% confidence interval as 3.140-57.650, 1.600-13.800, P<0.05). (3) Construction and evaluation of prediction model for PHLF. According to the multivariate analysis, preoperative portal vein tumor thrombus and preoperative ICG R15 were included to construct the prediction model for predicting the occurrence of PHLF in patients with hepatocellular carcinoma. The AUC, sensitivity, specificity of prediction model was 0.750 (95% confidence interval as 0.654-0.846, P<0.05), 0.551, 0.852, respectively. Conclusions:Preoperative portal vein tumor thrombus and preoperative ICG R15 ≥10% are independent risk factors influen-cing the occurrence of PHLF. The prediction model based on these two factors has good efficacy in predicting PHLF of patients with hepatocellular carcinoma.

Brain metastasis is a common complication of non-small cell lung cancer (NSCLC) patients. About 25%-55% of patients with NSCLC will develop brain metastases, and the occurrence of brain metastasis predicts a poor prognosis. Traditionally, radiotherapy, chemotherapy, targeted therapy and surgery are the main treatment options for NSCLC patients with brain metastases. In recent years, with the emergence of immune checkpoint inhibitors (ICI), the survival of NSCLC patients with brain metastases has been significantly improved. This article reviews the research progress of ICI treatment for NSCLC patients with brain metastases in order to provide new treatment strategies.

Influence of three different nucleic acid extraction methods on 2019-nCoV / 中华检验医学杂志

Objective:To study the difference in the extraction efficiency of the novel coronavirus (2019-nCoV) nucleic acid by using magnetic beads method, centrifugal column method and one-step method.Methods:On March 5, 2021, 10 throat swabs were collected from the staff working in the nucleic acid sampling room in Department of Clinical Laboratory, Affiliated Taikang Xianlin Drum Tower Hospital, Medical School of Nanjing University. The positive quality control samples were mixed into the swabs and used as mock positive samples. The RNA was extracted from simulated positive samples and their diluted samples by using magnetic beads method, centrifugation column method and one-step method. The purity ( A260/ A280 ratio) and concentration of the nucleic acid obtained were measured by micro-uv photometry, and fluorescence quantitative PCR was performed to compare the CT value and extraction efficiency. The three methods were used to extract the simulated weak positive specimens and to compare the difference of CT values after amplification. The measurement data that followed normal distribution were expressed by xˉ±s, the t test was used for comparing in the same group, and single factor analysis of variance was used for comparing among multiple groups. A P value smaller than 0.05 indicated a significant difference. Results:2019-nCoV nucleic acid extracted by magnetic bead method, centrifugal column method and one-step method could amplify positive results. There was no significant difference between the CT value of RNA amplification extracted by magnetic bead method and one-step method ( t=? 0.995 , P=0.376). The CT values of orf1ab gene amplified by centrifugal column method, magnetic bead method and one-step method were 29.28±0.06, 30.82±0.14 and 29.79±0.01 respectively ( F=11.196 , P=0.041). The CT values of E gene were 28.52±0.40, 27.33±0.78 and 27.38±0.13 respectively ( F=3.407, P=0.169). The CT values of N gene were 28.61±1.02, 27.24±0.20 and 27.25±0.47, respectively ( F=2.880 , P=0.020). The CT values of human genes extracted by centrifugal column method, magnetic bead method and one-step method were 19.68±0.36, 20.14±0.06 and 20.58±0.49 respectively, which was statistically significant ( F=4.904, P=0.048). The CT value of amplified human gene was affected by the dilution of human samples twice. The CT value of undiluted samples was smaller than that of diluted samples twice, with a difference of 2.95±0.22, which was statistically significant ( t=?3.025, P=0.039). The extraction time of one-step method, magnetic bead method and centrifugal column method were (15.00±1.50), (20.00±1.50) and (40.00±5.5) min respectively, and the difference was statistically significant ( F=688 , P=0.027). Conclusions:Magnetic bead method, centrifugal column method and one-step method can be used to extract 2019-nCoV nucleic acid, for the centrifugal column method has a higher extraction efficiency than the magnetic bead method and the one-step method. The one-step method is the fastest, followed by the magnetic bead method and the centrifugal column method. A large number of clinical samples can be processed using the magnetic bead method and one-step method. One-step rapid nucleic acid test can also be performed on samples from emergency and fever clinics. It is not recommended to dilute specimens for testing. In order to improve the detection rate, extracting RNA from highly suspected samples with negative initial nucleic acid test by centrifugal column method is suggested.

Cisplatin （3 mg·kg-1， ip， 5 days） was used to induce CIPN in mice. Administration began while modeling and lasted 12 days. The general conditions and behaviors of mice were observed. After the last administration， samples were collected. Pathological changes of the soles were observed based on hematoxylin-eosin （HE） staining. Biochemical assay was employed to determine the levels of serum superoxide dismutase （SOD）， hydrogen peroxide （H2O2）， malondialdehyde （MDA）， and nitric oxide （NO）， enzyme-linked immunosorbent assay （ELISA） the content of interleukin-6 （IL-6）， interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α）， and glutathione peroxidase-3 （GPX-3） in kidney tissue， and Western blotting the expression of extracellular signal-regulated kinase1/2 （ERK1/2）， phosphorylated-ERK1/2 （p-ERK1/2）， p38 MAPK， and phosphorylated-p38 MAPK （p-p38 MAPK） in kidney tissue. ResultCompared with the blank group， model group demonstrated obvious pathological damage on the soles， hyperkeratosis of the epidermis with a basketweave pattern， atrophy of stratum spinosum， reduction of cells， and intracellular edema. Compared with the model group， Fuzi Lizhongwan significantly alleviated the pathological damage of the skin tissue of the soles. The model group showed lower body weight， mechanical pain threshold， thermal pain threshold （P<0.01）， and SOD activity （P<0.05）， higher content of H2O2， MDA， and NO （P<0.01）， and higher expression of IL-6， IL-1β， and TNF-α （P<0.01） than the blank group. Fuzi Lizhongwan group demonstrated higher body weight， mechanical pain threshold， thermal pain threshold （P<0.01）， and SOD activity （P<0.05）， lower content of H2O2， MDA， and NO （P<0.05）， and lower expression of IL-6， IL-1β， and TNF-α （P<0.01） than the model group. The expression of ERK1/2， p-ERK1/2， p38 MAPK， and p-p38 MAPK increased significantly （P<0.01） in the model group compared with that in the blank group， while the expression decreased significantly （P<0.01） in the Fuzi Lizhongwan group compared with that in the model group. ConclusionFuzi Lizhongwan can relieve the neurological injury of cisplatin-induced CIPN mice and increase the pain threshold of mice， possibly by regulating the MAPK signaling pathway and inhibiting inflammatory response and oxidative stress.

Roles of Active Ingredients in Chinese Medicinals in Treatment of Acute Lung Injury by Regulating PI3K/Akt Signaling Pathway： A Review / 中国实验方剂学杂志

Acute lung injury is a common critical respiratory disease， which can further develop into acute respiratory distress syndrome （ARDS） with a high fatality rate， but there is no effective drug at present. Phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway is involved in cell proliferation， metabolism， survival， and motility through phosphorylation of numerous downstream effector molecules. It plays an important role in the development of acute lung injury by regulating mitochondrial function， apoptosis， autophagy， oxidative stress， and inflammatory response. The active ingredients in Chinese medicinals alleviate acute lung injury by targeting the PI3K/Akt signaling pathway. There has been an explosion of research on the treatment of acute lung injury by active ingredients in Chinese medicinals via PI3K/Akt signaling pathway， which is of great clinical research value. The article presented the first summary of studies exploring the correlation between PI3K/Akt signaling pathway and acute lung injury in recent years and summed up the protective effect of the active ingredients in Chinese medicinals against acute lung injury via PI3K/Akt signaling pathway， providing innovative mindsets and strategies for clinical application of active ingredients in Chinese medicinals in the treatment of acute lung injury.

Mechanism of hepatotoxicity induced by ethanol extract of Dysosma versipellis based on "quantity-weight-evidence" network toxicology / 中国中药杂志

In this study, the toxicological/pharmacological research method of "quantity-weight-evidence" network was first proposed and practiced to supplement the existing methodology of network toxicology. We transformed the traditional qualitative network into a quantitative network in this study by attributing weights to toxic component content and target frequency, which improved the reliability of data and provided a research idea for the systematic safety evaluation and toxicological research of Chinese medicinal herbs. Firstly, 50% ethanol extract of Dysosma versipellis(DV) was administrated to rats via gavage and the potential hepatotoxic components were identified by serum pharmacochemistry. Then, the component targets were obtained from SwissTargetPrediction, PharmMapper and other online databases, and the target weights were given according to the relative content of components and target fishing frequency. Meanwhile, the targets of hepatotoxicity were predicted from online databases such as Comparative Toxicology Database(CTD) and GeneCards. Subsequently, protein-protein interaction analysis and KEGG pathway enrichment were performed with the STRING database. Finally, the quantitative network of "toxic components-weighted targets-pathways" was constructed. Eleven potential toxic compounds were predicted, including podophyllotoxin, podophyllotoxone, deoxypodophyllotoxin, and 6-methoxypodophyllotoxin. A total of 106 hepatotoxic targets and 65 weighted targets(e.g., Cdk2, Egfr, and Cyp2 c9) were identified. The results of Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment showed that these targets could act on PI3 K-AKT, MAPK, and Ras signaling pathways to play a role in inflammatory response and oxidative stress. However, traditional network toxicology showed that 51 targets such as AKT1, Alb, and Stat3 may lead to hepatotoxicity by mediating inflammation and cell proliferation. In conclusion, we proposed "quantity-weight-evidence" network toxicology in this study and used it to study the mechanism of DV-induced hepatotoxicity in rats. This study confirms the feasibility of this new methodology in toxicological evaluation and further improves the systematic evaluation of the safety of Chinese medicinal herbs.

Construction and verification of a nomogram prediction model of severe adult community-acquired pneumonia / 中华危重病急救医学

Objective:To construct and verify the nomogram prediction model based on inflammatory indicators, underlying diseases, etiology and the British Thoracic Society modified pneumonia score (CURB-65 score) in adults with severe community acquired pneumonia (CAP).Methods:The clinical data of 172 adult inpatients first diagnosed as CAP at Taikang Xianlin Drum Tower Hospital from January 2018 to December 2021 were divided into severe and non-severe diseases groups according to the severity of their conditions. The baseline conditions (including gender, age, past history, comorbidities and family history), clinical data (including chief symptoms, onset time, CURB-65 score), first laboratory results on admission (including whole blood cell count, liver and kidney function, blood biochemistry, coagulation function, microbiological culture results) and whether the antimicrobial therapy was adjusted according to the microbiological culture results were recorded in both groups. Univariate analysis was used to screen for differential indicators between severe and non-severe patients. After covariate analysis, multi-factor Logistic regression analysis was performed based on the Aakaike information criterion (AIC) forward stepwise regression method to rigorously search for risk factors for constructing the model. Based on the results of the multi-factor analysis, a nomogram prediction model was constructed, and the discriminatory degree and calibration degree of the model were assessed using the receiver operator characteristic curve (ROC curve) and calibration curve.Results:A total of 172 adult CAP patients were included, 48 in severe group and 124 in non-severe group. The median age was 74 (57, 83) years old, onset time was 5.0 (3.0, 10.0) days, total number of comorbidities was 3 (2, 5), including 58 cases (33.7%) with hypertension and 17 (9.9%) with heart failure, 113 (65.7%) with CURB-65 score≤1, 34 cases (19.8%) had a CURB-65 score = 2 and 25 cases (14.5%) had a CURB-65 score≥3. Univariate analysis showed that there were statistically significant differences between the two groups in age, smoking history, CURB-65 score, heart rate, onset time, total comorbidity, pathogenic microorganisms, fibrinogen (FIB), D-dimer, C-reactive protein (CRP), procalcitonin (PCT), platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), and alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Multi-factor Logistic regression analysis showed that hypertension [odds ratio ( OR) = 3.749, 95% confidence interval (95% CI) 1.411 to 9.962], heart failure ( OR = 4.616, 95% CI was 1.116 to 19.093), co-infection ( OR = 2.886, 95% CI was 1.073 to 7.760), history of smoking ( OR = 8.268, 95% CI was 2.314 to 29.537), moderate to high CURB-65 score ( OR = 4.833, 95% CI was 1.892 to 12.346), CRP ( OR = 1.012, 95% CI was 1.002 to 1.022), AST ( OR = 1.015, 95% CI was 1.001 to 1.030) were risk factors for severe CAP (all P < 0.05). The filtered indicators were included in the nomogram model, and the results showed that the area under the ROC curve (AUC) for the model to identify patients with severe adult CAP was 0.896, 95% CI was 0.840 to 0.937 ( P < 0.05), and the calibration curve showed that the predicted probability of severe CAP was in good agreement with the observed probability (Hosmer-Lemeshow test: χ2 = 6.088, P = 0.665). Conclusions:The nomogram model has a good ability to identify patients with severe adult CAP and can be used as a comprehensive and reliable clinical diagnostic tool to provide a evidence for timely intervention in the treatment of adults with severe CAP.

Impact of Low Frequency Electro-acupuncture on Glucose and Lipid Metabolism in Unmarried PCOS Women: A Randomized Controlled Trial / 中国结合医学杂志

OBJECTIVE@#To explore the effect of electro-acupuncture (EA) on glucose and lipid metabolism in unmarried patients with polycystic ovary syndrome (PCOS).@*METHODS@#Fifty-four PCOS patients were equally randomized into true acupuncture group and sham acupuncture group (control) for totally 16 weeks of treatment by random method with a computerized randomization program. Patients in true acupuncture group accepted traditional acupuncture methods with EA and two sets of acupoint groups were used alternatively. The first set consisted of Zhongji (CV 3), Qihai (CV 6), Guilai (ST 29), Sanyinjiao (SP 6), Yinlingquan (SP 9), Hegu (LI4) and Baihui (GV 20), and the second set consisted of Tianshu (ST 25), ST 29, CV 3, CV 6, SP 6, Taichong (LR 3), Neiguan (PC) 6 and GV 20. Patients in the sham acupuncture group accepted shallow acupuncture methods through EA without electricity at 4 non-meridian points in each shoulder and upper arm. Outcome measures included body mass index (BMI), waist-hip-ratio (WHR), oral glucose tolerance test (OGTT), insulin release test, glucose and lipid metabolism indicators such as total cholesterol (TC), triglycerides, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, adiponectin, leptin, visfatin, resistin, and interleukin (IL-6).@*RESULTS@#Twenty-six subjects in the true acupuncture group and 20 subjects in the sham group completed the clinical trial. After 16 weeks of treatment, no significant difference in the outcome measures were observed between the two groups (P>0.05). However, as compared with baseline data, a reduction in weight, BMI, hipline, WHR, fasting glucose, homeostatic model assessment of insulin sensitivity, visfatin and HDL-C, and an increase in resistin and IL-6 were observed in the true acupuncture group (P<0.05). In addition, a reduction in visfatin and an increase in TC were also observed in the sham group (P<0.05).@*CONCLUSIONS@#Acupuncture may have a beneficial effect in the treatment of PCOS by improving glucose and lipid metabolism. Moreover, the sham acupuncture may be not completely ineffective. Sham acupuncture may improve some of the aspects of the glucose and lipid metabolism of PCOS patients through a placebo effect.

The treatment in the observation group was given once every 2 days, 3 times a week. Fluoxetine hydrochloride capsule was given orally in the control group, 20 mg each time, once a day. Treatment for 8 weeks was required in the both groups. The scores of Hamilton depression scale (HAMD) and modified Kupperman scale were observed in the both groups before and after treatment, and at 1, 3, 6-month follow-up. The therapeutic efficacy was evaluated after treatment.@*RESULTS@#Compared before treatment, the scores of HAMD and modified Kupperman scale after treatment and at each time point of follow-up were decreased in the both groups (@*CONCLUSION@#Acupuncture combined with wheat-grain moxibustion can effectively treat perimenopausal depression with kidney deficiency and liver depression, and have more stable and sustained therapeutic effect compared with oral fluoxetine hydrochloride capsule.

Screening result analysis of diabetes in high-risk population in Songjiang District of Shanghai, 2016-2017 / 上海预防医学

Objective To investigate the prevalence of diabetes and impaired glucose regulation in high risks community residents in Songjiang District of Shanghai, and to explore the risk factors affecting their blood glucose metabolism, providing effective suggestions for improving community diabetes prevention and treatment. Methods Questionnaire, physical examination and laboratory testing were used to collect information on the basic characteristics and blood glucose levels of 21 035 residents in Songjiang District who were assessed to be at high risk of diabetes. Results A total of 3 008 people with impaired regulation and 2 241 patients with diabetes were detected.The detection rates were 14.3% and 10.6%, respectively.It was found that as the residents′ age was higher, their education level was lower, high-risk factors for them were numerous, and their detection rates of diabetes and impaired sugar regulation were higher.It was found that age, gender, history of impaired glucose regulation, relatives with type 2 diabetes, hypertension, dyslipidemia and overweight/obesity were all factors influencing blood glucose metabolism (P < 0.05). Conclusion Blood glucose screening in high-risk population of diabetes is helpful for the early detection of diabetic patients and those with impaired glucose regulation.It is necessary to strengthen the attention of population at risk of diabetes and take appropriate interventions.

Pharmacodynamic Basis of Jinqi Jiangtang Tablets in Treatment of Type 2 Diabetes Based on LC-MS and Molecular Docking Strategy / 中国实验方剂学杂志

Objective::Based on LC-MS and molecular docking strategy, to study the pharmacodynamic material basis of Jinqi Jiangtang tablets in the treatment of type 2 diabetes mellitus(T2DM). Method::UPLC-Q-TOF-MS was used to identify the chemical constituents of Jinqi Jiangtang tablets. On this basis, the disease targets were screened based on the online disease target database and protein-protein interaction(PPI). The molecular docking technology was used to verify the relationship between the chemical constituents and disease targets in Jinqi Jiangtang tablets, so as to find out the potential pharmacodynamic basis of Jinqi Jiangtang tablets in the treatment of T2DM. Result::Based on UPLC-Q-TOF-MS, 51 chemical constituents were identified in Jinqi Jiangtang tablets, including 31 astragalus, 16 coptis and 4 honeysuckle. The key targets of catalase from micrococcus lysodeiktic(CAT) receptor, peroxisome proliferative actived receptor(PPARG) receptor and insulin(INS) receptor were identified by CTD database, topological analysis and related literature. Based on LC-MS and molecular docking technology, we found that magnoflorine, coptisine, epiberberine, astragaloside Ⅳ, caffeic acid, palmatine, berberine, jateorhizine, berberubine, berberastine, groenlandne, lycoranine B, demethyleneberberine, isomucrontolula-7-O-glucoside and calycosin-7-O-glucoside were used to treat type 2 diabetes potential pharmacodynamic material basis of urinary diseases. Conclusion::Protein interaction and network topology analysis are helpful for the rapid localization of core targets. In addition, molecular docking technology can realize large-scale virtual screening of potential candidate compounds. The integration of LC-MS and molecular docking technology can facilitate and quickly find the potential pharmacodynamic substance basis in traditional Chinese medicine prescriptions, and provide a reference for subsequent drug activity screening experiments.
